If the federal reserve decreases the reserve rate from 5% to 2% how does this affect the amount of money that would result because of fractional reserve banking from an into Al deposit in a bank of 25000

Answer:

The probability that exactly 5 of the 7 selected smartphone users use their phones in meetings or classes is approximately 0.0127 or 1.27%.

As a result, the likelihood that the mean length of a random sample of 17 items is less than 10.9 inches is about 0.9265, or 92.65%.

Probability is a measure of how likely an event is to occur. It is a number between 0 and 1, with 0 suggesting that an occurrence is impossible and 1 indicating that an event is unavoidable. A given event's probability is computed by dividing the number of positive outcomes by the total number of potential possibilities.

In this case, we may utilize the central limit theorem to estimate the sample mean distribution. The central limit theorem states that if the sample size is high enough (n 30), the distribution of the sample mean will be normal.

Regardless of demographic distribution, the population is essentially typical.

In this scenario, the population has a normal distribution with a mean () of 9.8 inches and a standard deviation () of 2 inches. We wish to calculate the likelihood that the sample mean (x) of 17 objects is smaller than 10.9 inches.

The formula for calculating a sample mean's z-score is: z = (x - ) / ( / sqrt(n)), where n is the sample size.

We obtain: z = (10.9 - 9.8) / (2 / sqrt(17)) by substituting the numbers supplied in the problem.

z = 1.45

We may calculate the chance that a standard normal variable is smaller than 1.45 using a typical normal distribution table or calculator:

P(Z < 1.45) = 0.9265

If Astrid says the function being graphed is y=-4+1/3. Matt is correct, while Astrid is incorrect.

Astrid's equation y = -4 + 1/3 is incorrect because it is missing the variable x. The equation is missing a term that represents the x variable, so the equation does not represent a line.

On the other hand, Matt's equation y = 1/3x is correct, and the slope of the line represented by this equation is indeed 1/3. This can be seen from the fact that the equation is in the form y = mx, where m is the slope of the line. In this case, m = 1/3, so Matt is correct.

Answer:

Write the whole number as a fraction by placing it over 1. For example, if you want to multiply 2/5 by 3, you can write 3 as 3/1.

Multiply the numerators of the two fractions together. For example, 2/5 x 3/1 = (2 x 3) / 5 = 6/5.

Simplify the resulting fraction, if necessary, by reducing it to its lowest terms. For example, 6/5 can be simplified to 1 1/5 (or 1.2 as a decimal).

Therefore, when you multiply a fraction by a whole number, you multiply the numerator of the fraction by the whole number and keep the denominator the same.

Answer:

Step-by-step explanation:

We can start by writing the given equation in terms of polar form:

Re(z1,z2-bar) = modulus of z1 * modulus of z2

If we write z1 and z2 in polar form, we get:

z1 = r1(cosθ1 + i sinθ1)

z2 = r2(cosθ2 + i sinθ2)

Then, the conjugate of z2 is:

z2-bar = r2(cosθ2 - i sinθ2)

Using the formula for the real part of the product of two complex numbers, we get:

Re(z1,z2-bar) = Re(z1 * z2-bar)

Substituting the expressions for z1 and z2-bar, we get:

Re(z1,z2-bar) = Re(r1(cosθ1 + i sinθ1) * r2(cosθ2 - i sinθ2))

Simplifying the product, we get:

Re(z1,z2-bar) = Re(r1r2[(cosθ1 cosθ2 + sinθ1 sinθ2) + i(sinθ1 cosθ2 - cosθ1 sinθ2)])

The real part of this expression is:

Re(z1,z2-bar) = r1r2(cosθ1 cosθ2 + sinθ1 sinθ2)

Using the identity cos(θ1 - θ2) = cosθ1 cosθ2 + sinθ1 sinθ2, we can write:

Re(z1,z2-bar) = r1r2 cos(θ1 - θ2)

Now we can substitute this expression back into the original equation and get:

r1r2 cos(θ1 - θ2) = r1r2

Dividing both sides by r1r2, we get:

cos(θ1 - θ2) = 1

This equation is true if and only if θ1 - θ2 = 2πn for some integer n. In other words, θ1 = θ2 + 2πn, where n is an integer.

Therefore, we have proved that Re(z1,z2-bar) = modulus of z1 * modulus of z2 if and only if arg z1 = arg z2 + 2πn, where n is an integer.

Answer:21>15+2x

Step-by-step explanation:

The product of -2³ + x - 5 and x³ -3x +4 is -5x³ + 16x - 28.

The given expression is:

-2³ + x - 5 x (x³ -3x +4)

We need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's simplify -2³, which means -2 x 2 x 2 = -8, so we have:

-8 + x - 5 x (x³ -3x +4)

Next, we need to distribute the -5 to the terms inside the parentheses:

-8 + x - 5x³ + 15x - 20

Now we can combine like terms:

-5x³ + 16x - 28

Therefore, the product of -2³ + x - 5 and x³ -3x +4 is -5x³ + 16x - 28.

Now, to answer the second part of the question, we need to check if:

-2³ + x - 5 x (x³ -3x +4) = (x³ -3x +4) * (-2³ + x - 5)

We can simplify both expressions first:

-8 + x - 5x³ + 15x - 20 = -8 + x - 5x³ + 15x - 20

We can see that both expressions are identical, which means that the product of -2³ + x - 5 and x³ -3x +4 is equal to the product of x³ -3x +4 and -2³ + x - 5, regardless of the order in which we multiply the factors.

Answer:

C) 260 square inches.

Step-by-step explanation:

To find the surface area of a pyramid, we can use the formula.

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

where l is the length of one side of the square base, s is the slant height, and Base Area is the area of the square base.

In this case, the base of the pyramid is a square with side length l = 10 inches, so its area is

Base Area = l^2 = 10^2 = 100 square inches

To find the perimeter of the base, we can simply multiply the length of one side by 4

Perimeter of Base = 4l = 4 x 10 = 40 inches

We are also given that the slant height of the pyramid is s = 8 inches.

Now we can substitute the values into the formula.

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

Surface Area = (1/2) x 40 x 8 + 100

Surface Area = 160 + 100

Surface Area = 260 square inches

Therefore, the surface area of the pyramid is 260 square inches.

Step-by-step explanation:

we can see that a larger proportion of male students preferred mathematics (0.48) compared to female students (0.22), while a larger proportion of female students preferred English (0.18) compared to male students (0.12).

HOW TO SOLVE THE QUESTION?

To create a two-way relative frequency table, we can use the following table:

       | English | Mathematics | Total

--------|---------|-------------|-------

Male    |   x     |     24      |   30

Female  |   y     |     11      |   20

--------|---------|-------------|-------

Total   |   35    |     35      |   50

Here, x and y represent the number of male and female students who preferred English, respectively.

To calculate the values for x and y, we can use the fact that there were 35 students who preferred mathematics, and 24 of them were male. Therefore, the number of females who preferred mathematics is 35 - 24 = 11. Since there are a total of 20 female students, the number of females who preferred English is 20 - 11 = 9. Similarly, the number of male students who preferred English is 30 - 24 = 6.

To calculate the relative frequencies, we can divide each cell by the total number of students (50). For example, the relative frequency of male students who preferred mathematics is 24/50 = 0.48.

The resulting two-way relative frequency table is as follows:

       | English | Mathematics | Total

--------|---------|-------------|-------

Male    |   0.12  |     0.48    |  0.60

Female  |   0.18  |     0.22    |  0.40

--------|---------|-------------|-------

Total   |   0.30  |     0.70    |  1.00

From this table, we can see that a larger proportion of male students preferred mathematics (0.48) compared to female students (0.22), while a larger proportion of female students preferred English (0.18) compared to male students (0.12). However, it would not be safe to assume that all females prefer English and all males prefer mathematics based on this data alone, as there may be individual variations and exceptions to this trend.

It's also important to note that the sample size is relatively small, with only 50 students surveyed, and may not be representative of the larger population. Further research with a larger and more diverse sample size would be needed to make more accurate conclusions about gender-based preferences in this population

Answer:

To find the total balance after three years, we can use the formula for continuous compounding:

A = Pe^(rt)

Where A is the total balance, P is the principal (initial amount), e is Euler's number (approximately 2.71828), r is the annual interest rate as a decimal, and t is the time in years.

In this case, P = $12,000, r = 0.0125 (1.25% expressed as a decimal), and t = 3. Plugging these values into the formula, we get:

A = $12,000 x e^(0.0125 x 3)

A = $12,000 x e^(0.0375)

A = $12,000 x 1.038163

A = $12,458.54

Therefore, the total balance after three years is $12,458.54.

Answer:

∂z/∂x = 3x^2 + 6y

∂z/∂y = 6x - 3y^2

Now, we need to solve the system of equations:

3x^2 + 6y = 0

6x - 3y^2 = 0

From the first equation, we get:

y = -x^2/2

Substituting this into the second equation, we get:

6x - 3(-x^2/2)^2 = 0

Simplifying, we get:

6x - 3x^4/4 = 0

Multiplying by 4 and rearranging, we get:

3x^4 - 24x = 0

Factoring out 3x, we get:

3x(x^3 - 8) = 0

Therefore, the critical values of x are x = 0 and x = 2.

For x = 0, we have y = 0 (from y = -x^2/2). So, one critical point is (0, 0).

For x = 2, we have y = -2. So, the other critical point is (2, -2).

To find the critical values of the function, we need to evaluate the function at each critical point:

z(0, 0) = 0^3 + 6(0)(0) - 0^3 - 1 = -1

z(2, -2) = 2^3 + 6(2)(-2) - (-2)^3 - 1 = -13

Therefore, the critical values of the function are -1 and -13.

The angle x opposite to the side measuring 17 is approximately 20.68 degrees using trigonometry.

Let x stand for the side that is the shortest. The Pythagorean theorem yields the following result: x2 + 172 = 19.

When we simplify this equation, we obtain:

[tex]x^2 = 19^2 - 17^2[/tex]

[tex]x^2 = 36x = 6[/tex]

Hence, the shortest side is six inches long.

Using the inverse trigonometric function tangent, we can determine the angle opposite the side measuring 17. (tan).

tan = adjacent/opposite = x/17

The percent increase in the amount of interest paid between a household with a 780 credit score and one with a 589 credit score is approximately 0.8%, which is closest to option B, 0.8% or 39.9%.

Finding the entire amount paid by each family and comparing the difference in total amount paid will allow us to determine the percentage rise in the amount of interest paid between a household with a credit score of 780 and one with a score of 589.

The overall cost for a FICO score of 780 is:

$12,650 for the principal balance and all installments plus (33 x $60) to get $14,930.

With a 589 FICO score, the total cost is:

Total payments plus principal balance equal $12,650 plus (40 x $60) = $15,050.

The two households' combined total outlays differ in the following ways:

$15,050 - $14,930 = $120

We multiply by 100 and divide the difference by the initial sum to determine the percent increase:

($120 / $14,930) x 100% = 0.802% ≈ 0.8%

In light of this, the difference in interest rates between a family with a 780 credit score and one with a 589 credit score is roughly 0.8%, which is closest to option B, 0.8% or 39.9%.

Answer: To find the average of x, y, and z in terms of m, we first need to find expressions for x, y, and z in terms of m:

x = (m + 9)/2

y = (2m + 15)/2

z = (3m + 18)/3 = (m + 6)

To find the average of x, y, and z, we add them up and divide by the number of terms:

average = (x + y + z)/3

Substituting the expressions for x, y, and z, we get:

average = [(m + 9)/2 + (2m + 15)/2 + (m + 6)]/3

Simplifying the expression by combining like terms, we get:

average = (4m + 30)/6

Simplifying further by dividing both the numerator and denominator by 2, we get:

average = (2m + 15)/3

Therefore, the average of x, y, and z in terms of m is (2m + 15)/3.

The assertion that the percentage of males who own cats is lower than the percentage of women who do not own cats is unsupported by sufficient data.

Hence, the Alternate hypothesis would be:

Alternate hypotheses are used in statistical hypothesis testing. The hypothesis of a test always predicts no effect or no association between variables, but the alternative hypothesis reflects the effect or relationship that your research predicts.

Given information:

The test claims proportion of men who owns cat is smaller.

The significance level = 0.005

As the hypothesis always gets ten statements of equality but in the case given alternate hypothesis will claim.

Now calculating the Z-value:

P= 10+14/80

So, the p-value according to the obtained Z value is 0.1365.

Since, 0.1365>0.005, we fail to reject the hypothesis.

The interest earned by Sarah in four (4) years is approximately $62.16.

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given that;

First, we convert R as a percent to r as a decimal

r = R/100

r = 7/100

r = 0.07

Now, the the values into the above formula and solve for accrued amount (A).

A = P( 1 + r/n )^( n × t )

A = $200( 1 + 0.07/1 )^( 1 × 4 )

A = $200( 1 + 0.07 )^( 4 )

A = $200( 1.07 )^( 4 )

A = $262.16

Now, we know that;

Accrued amount (A) = Principal (P) + Interest (I)

Solve for Interest (I)
